AI Logic for Gale's Redirection

[Northmoc]

Hmm, I don't remember anything already in ChangeZoneAi in particular, it'll probably need a hook to a standard counter logic (along the lines of "if AILogic is set to CounterSpell, then run a check for the counter logic and, if it succeeds, agree to play the spell targeting whatever is on the stack"). Might look into in but need a little bit more time than currently available... :/
